The father-in-law of the male lead in the novel is called Shen Baichuan

Answer 1

If the father-in-law of the male protagonist in the novel was called Shen Baichuan, then the plot of the novel might involve the following aspects:

Shen Baichuan was a wealthy businessman who had business dealings with the male lead.
2. Shen Baichuan is very concerned about the male lead and may often give support and help.
3. Shen Baichuan might have some unknown secrets related to the male lead.
4. The male lead may receive some mysterious treatment in Shen Baichuan's house or be related to some mysterious items in Shen Baichuan's house.

The above was just a guess. The specific plot still needed to be determined according to the plot and setting of the novel itself.
